POTATO-PARING MACHINE.

SPECIFICATION forming part. of Letters Patent No. 362,009, dated April 26, 1887.

Application filed July 17, 1886. Serial No. 208,279. (No model.)

To all whom it may concern:

Be it knownthat I, HENRY J. HYER, acitizen of the United States, residing at Unadilla, in the county of Otsego and State of New York, have invented a new and useful Improvement in Potato-Faring Machines, of which the following is a specification.

In my improved potato-paring machine the potatoes are placed within the paring-cylinder, and are kept wet with water while the skin is being'removed. The cylinder has means provided for the charging and discharging of the potatoes, and to enable theinready inspection while being pared.

My invention particularly consists in certain details of construction of the machine, which will be first described with reference to the accompanying drawings, and then specifically pointed out in the claims.

In said drawings, Figure I is an elevation of one end of the potato-paring machine. Fig. II is an elevation of the other end thereof. Fig. III is a side elevation, the cover being shown in section. Fig. IV is a vertical axial section. Fig. V is a plan view to a larger scale of one of the plates of the paring-cylinder. Fig. VI is an inside view of one of the cylinder-heads.

The shaft 1, on which the paring-cylinder is mounted, is journaled at its ends in the frame 2, which may stand upon the floor, as shown. Between the sides of the frame is supported a trough, 8, for containing water,which rests on cross-braces 4 of the frame 2, as shown in Figs. III and IV. A two-part shield or cover, 5, opening at tog, is hinged at the sides of the trough, and, surrounding the paring-cylinder, prevents water and gratings from being thrown outward and away from the machine.

The paring-cylinder is made up ofa number of rings or sections, 6 7 8 9. 9 are fixed to their adjacent ends or heads 10 11 of the cylinder. The head 10 is fixed by screw or otherwise rigidly to the shaft 1. The section Sis also made rigid with said shaft, being supported therefrom by spokes or arms 12. The head 11, however, runs loosely on the shaft 1, and the section 7 is rigidly connected with section 9 on said head by means of arms 13. The sections 6 and 8 are thus adapted to move together, and the sections 7 The sections 6 and and 9 together. The sections 6 and 8 move with the shaft when operated by the crank 14; but the sections 7 and 9 are turned in theopposite direction by means of the reversinggear shown in Fig. I, in which 15 is a gearwheel rigid with the shaft 1. 16 is a pinion journaled on a stud projecting inwardly from the frame 2 and gearing with the wheel 15, and 17 is a rack internally toothed and rigid with the head 11 of the cylinder, and consequently with the sections 7 and 9. In this manner the alternate sections of the cylinder are forced to rotate in opposite directions.

In order to support the weight of section 7, the head 11 is formed with an elongated hub 18, which thus lessens the friction and wear on shaft 1 at the point surrounded by said head.

The heads of the cylinder are made with numerous holes, so as to be sufficiently open to permit water to flow freely from the trough 3 into the cylinder. The water also flows freely between the sections of the cylinder and through perforations in its side.

The sections of the cylinder are preferably formed as illustrated in Figs; III, IV, and V. Each section consists of two metal rings, 19, to which are riveted a number of plates, 20, perforated, as shown in Figs. III and V, and having a pyramidal or conical inward projec tion, 21, pressed therein. I have shown the projection 21 as pyramidal in form; but it is obvious that the conical form may be adopted with good results, one object being to form a surface which inclines toward the edge of the section, as shown in Fig. IV, so that the p, vegetables being operated upon will roll into the crack between two adj acentsections, and be subjected to the action of both. It will be observed that this figure shows in section the oppositely-inclined grating-surfaces of but two of the grating-rings, (to wit, 7 and 9,) while through the summit of a protuberance on one grating-ring it will pass between two adjacent protuberances on the adjacent grating-ring. The entire surface of plates 20 and the proectlons 21 are covered with perforations, as shown, adapting the said plates and projections on adjacent sections of the cylinder to act as graters on different sides of a potato at the same time. The edges of the plates 20, which are next to the cylinder heads 11, are carried onto the inside edges of said cylinderheads, (see Fig.VI,) thus completing a gratingsurface that quickly and effectually removes the skin from the potatoes. The water, rushing through the heads of the cylinder between the sections thereof and through the perforationsin the plates and projections 21, keep the said perforations entirely clear of skin.

It will be observed that by making a section of the cylinder, as thus described, any portion thereof can be removed or replaced at pleasure.

One head of the cylinder, preferably that toward the crank 14, is provided with a door, 22, opening downward and hinged, as shown, to permit access to the interior of the cylinder for charging with potatoes or removing the same.

The water is drawn from the trough by a plug, 23, as shown in Fig. II.

The spokes 12 are covered with a tin gratersurface, soldered thereto, if preferred.

I am aware that it has been proposed to construct a potato-parer of a pair of oblate hemispherical cups having inwardly projecting burrs, and provided with interior conical proectlons having outwardly-projecting burrs, the said cups being placed mouth to mouth and attached, respectively, to a shaft and a' hollow sleeve concentric therewith, suitable gearlng being provided whereby said cups are rotated in opposite directions about a common axls. Such I do not claim; nor is it the equivalent of my parer, which consists of a cylinder made up of any desired number of sections and means whereby the adjacent sections are rotated about a common axis in opposite directions. In machines of the character to which my invention relates the paring action .13 produced in greater part (if not wholly) by the action of the oppositely-moving gratingsurfaces upon the vegetables being pared; hence the capacity of such a device as above disclaimed, having but two oppositely-moving faces, is necessarily limited, whereas the capacity of my machine may be increased indefinitely by increasing the number of sections of which the paring-cylinder is made up.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. In a potato-parer, the combination, with a plurality of paring-sections and means for rotating them in one direction, of an intervening paring-section and means for rotating it in the opposite direction, substantially as and for the purpose set forth.

2. In a potato-parer, the combination, with a series of rings or circular sections having abrading or grating surfaces and means for rotating them in one direction, of a second series of abrading rings or sections and means for rotating them in a direction opposite to the movement of the first series, the several sections of one series being interposed between the several sections of the other series, substantially as set forth.

3. In a potato-parer, the combination of a series of rings, each having on its interior a gratingsurface inclined toward both edges, as shown and described, and means for rotating the adjacent rings in opposite directions, substantially as and for the purpose set forth.

4. The combination, with a rotatable shaft and a grating-section fixed thereto, of a pair of gratingsections located upon opposite sides of the section first named and supported by said shaft so as to turn thereon, and means for turning said pair of grating-sections in a direction opposite to the movement of the section first named, substantially as set forth.

5. In combination with the shaft of apo tato-paring machine, a cylinder mounted thereon composed of perforated sections made up of separate plates and each of said plates having an inward projection, substantially as set forth. 6. In combination with the shaft of a potato paring machine, a sectional cylinder mounted thereon, whose alternate sections are connected by arms or cross-pieces and run loosely on said shaft, while the remaining sections are fixed to the shaft, and suitable gearing whereby each section is revolved in an opposite direction to its neighbor, substantially as set forth.

7. In combination with the supporting- ICC frame of a potato-paring machine and the connected with said shaft provided with a rough grater-surface, as set forth.

9. The combination, with the rotatable shaft 1 and the grating-sections 6 and 8, secured thereto, of the head 11, mounted to turn upon said shaft, the gratingsections 7 and 9, connected to said head, the pinion 18, secured to said shaft, and reversing-gear connecting said pinion with the head 11, substantially as and for the purposes set forth.
